Linux 32 or 64 bit?

Question

How to know if the linux I’m using is 32 bits or 64 bits?

I need to know what the architecture of my kernel is and I’m new to linux, I’d like to know how to figure it out.

Answer 1

Try uname -m. Command will give you the following exit:

x86_64 ==> 64-bit kernel
i686   ==> 32-bit kernel

With that you’ll know.

Answer 2

Type the command in the terminal arch. You will receive a result like this ia64 or x86_64 for 64 bits or i686 32-bit.
